Part 1 — The Complete Journey We start at the furnace, not the gate. Because the part carries its history. Hydrogen absorbed in the melt. Air entrained in a rushed slow shot. Residual stress locked in during solidification. All of it shows up later — usually at the worst possible moment. We walk through furnace practice, machine architecture, shot ratio, die spray, plunger lubrication, slow shot, fast shot, intensification, and solidification. The goal is understanding why each step matters, not just memorizing the settings.

Part 2 — Die Meets Machine This is where the math and the metal shake hands. PQ² analysis — the engineering handshake between your die design and the machine's capability — tells you whether what you designed will actually run. We cover fan and tangential runner design, overflow sizing, vent area calculation, vacuum systems, freeze blocks, and simulation strategy. There's also an expanded section on modern AI-assisted defect prediction, building on the foundation Mike Ward established in the original NADCA Gating Manual.
